Answer:
5.625 inches
Step-by-step explanation:
Given that:
Total Rainfall in inches (P) = 8 inches
The runoff volume (in inches) Q = ???
The curve number CN = 80
Recall that: The runoff volume can be calculated by using the formula:
for P > 0.2S
Q = 0 for P < 0.2S

where:
curve number CN = 80

S = 2.5 inches
Since the rainfall (P) is greater than 0.25
Then:




Q = 5.625 inches
Thus, the runoff volume = 5.625 inches
Answer:
The numbers that represent this situation are 7 and 9.
Step-by-step explanation:
For this problem, we have to find two numbers that sum up to 16 and have a difference of 2.
First, let's list out the numbers the sum up to 16.
1 + 15
2 + 14
3 + 13
4 + 12
5 + 11
6 + 10
7 + 9
From this list, we can see that 7 and 9 are our numbers. 7 and 9 sum up to 16. When you subtract 7 from 9, then you will get a difference of 2.
<u>So, two numbers that have a sum of 16 and a difference of 2 are 7 and 9. </u>
